Looking at a JSM 50?
Population figures cannot tell you whether one particular car is taxed, MOT-valid or safe to buy.
Check its registration free for the official tax, MOT and mileage record. If the car is still worth pursuing, the optional £9.99 full history check adds outstanding-finance, stolen and insurance write-off checks.
Wondering whether one particular JSM 50 is off the road? A free SORN check shows whether it is currently SORN, taxed or untaxed.
Is the JSM 50 disappearing?
Licensed numbers peaked at 182 in 2021 Q2 and stand at 42 in 2026 Q1, down 77%. That is down 73% in the five years since 2021 Q1.
A falling population is worth knowing before you buy: it usually means fewer donor cars, fewer specialists and slower parts supply, and it is why a good example of a scarce model can hold its price while a neglected one is hard to sell at any price.
